Referring to FIG. 1 to FIG. 5, a control method for an electronic device 100 is provided according to an embodiment of the disclosure. The electronic device 100 includes a transparent display screen 13 and an infrared sensor 161. The transparent display screen 13 includes a display area 131. The infrared sensor 161 is stacked below the display area 131. The infrared sensor 161 is configured to emit infrared light and receive infrared light reflected by an object to detect a distance between the object and the electronic device 100. With the stacking arrangement, the infrared sensor 161 is disposed below the display screen 13 in a case that the electronic device 100 is placed horizontally. The method includes operations as follows.

At S10, it is determined whether the electronic device is in an outgoing call state.

At S20, control is performed to reduce brightness of the transparent display screen in a case that the electronic device is in the outgoing call state.

At S30, control is performed to turn on the infrared sensor to detect a distance between the object and the electronic device.

A control device 200 for an electronic device 100 is provided according to an embodiment of the disclosure. The control method for the electronic device 100 according to the embodiment of the disclosure may be implemented by the control device 200 according to the embodiment of the disclosure. The control device 200 includes a judgment module 21 and a control module 22. S10 may be implemented by the judgment module 21, and S20 may be implemented by the control module 22. That is, the judgment module 21 is configured to determine whether the electronic device 100 is in an outgoing call state. The control module 22 is configured to perform control to reduce the brightness of the transparent display screen 13 in a case that the electronic device 100 is in the outgoing call state, and perform control to turn on the infrared sensor 161 to detect a distance between the object and the electronic device 100.

An electronic device 100 is provided according to an embodiment of the disclosure. The electronic device 100 includes a transparent display screen 13, an infrared sensor 161 and a processor 10. The transparent display screen 13 includes a display area 131. The infrared sensor 161 is stacked below the display area 131. The infrared sensor 161 is configured to emit infrared light and receive an infrared light reflected by an object to detect a distance between the object and the electronic device 100. S10, S20 and S30 may be implemented by the processor 10. That is, the processor 10 may be configured to determine whether the electronic device 100 is in an outgoing call state, perform control to reduce the brightness of the transparent display screen 13 in a case that the electronic device 100 is in the outgoing call state, and perform control to turn on the infrared sensor 161 to detect a distance between the object and the electronic device 100.

A computer device 300 is provided according to an embodiment of the disclosure. In the embodiments of the disclosure, the control device 200 may also be applied to the computer device 300. The computer device 300 may be a mobile phone, a tablet, a laptop, a smart bracelet, a smart watch, a smart helmet, smart glasses, a game machine or the like. The electronic device 100 according to the embodiments of the disclosure may also be one of the computer devices 300.

A mobile phone is taken as an example of the electronic device 100 in the embodiment of the disclosure for illustration. An infrared sensor is generally disposed at a top position of a screen of the mobile phone to determine a distance between the mobile phone and an obstacle, and make adjustment, thereby preventing misoperation of a user and saving power of the mobile phone. When a user answers or makes a call, the infrared sensor is turned on for distance detection. When the user makes the mobile phone approaching the head, the infrared sensor generates detection information by calculating time elapsed from a time instant when an emitter emits infrared light to a time instant when reflected infrared light is received by a receiver, or generates detection information based on the intensity of the infrared light emitted by the emitter and the intensity of the reflected infrared light received by the receiver. The processor transfers an instruction to a controller based on the detection information, and the controller controls the screen to be in a blanked state in response to the instruction. The screen may include for example an LCD screen and an OLED screen. For the LCD screen, the controller may control a backlight of the LCD screen to be turned off in response to the instruction. For the OLED screen, the controller may control pixels not to illuminate in response to the instruction. When the mobile phone is brought away from the head, the processor transfers an instruction to the controller based on detection information fed back by the infrared sensor, and the controller lights up the screen in response to the instruction.

With the development of mobile phones, bezel-less phones have become a new development trend. In order to raise an occupation proportion of a screen in the mobile phone, an infrared sensor is stacked in an area below a display screen. When a user makes a call, and the infrared sensor stacked below the screen is turned on and emits infrared light for distance detection. The infrared light emitted by the infrared sensor irradiates a TFT substrate of the display screen. Due to a photoelectric effect, under irradiation of the infrared light, electrons inside the TFT substrate are excited by infrared photons to form a current. An infrared light pulse is emitted by the infrared sensor, which results in occurrence of a flickering phenomenon in the display screen.

With the control method according to the embodiment of the disclosure, it is determined whether the electronic device 100 is in an outgoing call state first. Control is performed to reduce the brightness of the transparent display screen 13 in a case that the electronic device 100 is in the outgoing call state. Control is performed to turn on the infrared sensor 161 to detect a distance between the object and the electronic device 100. In this way, when an outgoing call is made at the electronic device 100, the brightness of the screen is reduced before the infrared sensor 161 is turned on, thereby weakening a flickering of the screen caused by the infrared sensor 161.

Referring to FIG. 6, whether the electronic device 100 is in an outgoing call state may be determined by detecting whether a dialing key of a dialing interface is touched by a user. Referring to FIG. 7, after the user clicks the dialing key, it is indicated that an outgoing call is made at the electronic device 100. In this case, the electronic device 100 is in the outgoing call state, the user generally does not need to view the transparent display screen 13, and the brightness of the transparent display screen 13 can be appropriately reduced, and the infrared sensor 161 is turned on for distance detection. In this case, the flickering of the transparent display screen 13 caused by the infrared sensor 161 is weakened.

It will be appreciated that in a case that the electronic device 100 is not in the outgoing call state, the electronic device 100 is kept in an original state and determines whether the electronic device 100 is in the outgoing call state again.

It should be noted that the control method according to the embodiment of the disclosure is also applied to a situation where there is an incoming call at the electronic device 100. Specifically, it may be detected whether the user answers the incoming call. When there is an incoming call at electronic device 100, information on the incoming call is displayed on the transparent display screen 13, and the user determines whether to answer the call by checking the information on the incoming call. After the user clicks an answer key, the user generally does not need to view the transparent display screen 13 at this time, and the brightness of the transparent display screen 13 may be appropriately reduced, and then the infrared sensor 161 is turned on for distance detection. It will be appreciated that the outgoing call state or the outgoing call also includes the form of outgoing calls in other voice call applications, and the incoming call state also includes the form of incoming calls in other voice call applications.

Further, referring to FIG. 3, FIG. 4 and FIG. 8, in such an embodiment, S20 that control is performed to reduce the brightness of the transparent display screen 13 includes operations as follows.

At S210, it is determined whether the electronic device is approaching a user.

At S220, control is performed to reduce the brightness of the transparent display screen in a case that the electronic device is approaching the user.

Further, in such an embodiment, S210 may be implemented by the judgment module 21, and S220 may be implemented by the control module 22. That is, the judgment module 21 is configured to determine whether the electronic device 100 is approaching a user. The control module 22 is configured to perform control to reduce the brightness of the transparent display screen 13 in a case that the electronic device 100 is approaching the user.

Further, in such an embodiment, the processor 10 of the electronic device 100 may implement 5210 and S220. That is, the processor 10 is configured to determine whether the electronic device 100 is approaching a user, and reduce the brightness of the transparent display screen 13 in a case that the electronic device 100 is approaching the user.

When the electronic device 100 is approaching the user, the user generally does not need to view the transparent display screen 13, and the user prepares for a call and waits for the other party to answer, alternatively, the other party has been connected, and the user is approaching the electronic device 100 for entering the call state. Therefore, when the electronic device 100 is approaching the user, the brightness of the transparent display screen 13 may be appropriately reduced, and the infrared sensor 161 is turned on. In this way, the flickering of the transparent display screen 13 caused by the infrared light emitted by the infrared sensor 161 can be weakened.

It will be appreciated that the user may perform other operations in a case that it is detected that the electronic device 100 is in the outgoing call state and is brought away from the user. In this case, the brightness of the transparent display screen 13 may be restored for facilitating next operations of the user. In a case that it is detected that the electronic device 100 is in the outgoing call state and is approaching the user again, the brightness of the transparent display screen 13 is reduced again.

In addition, in a case that it is determined that the electronic device 100 is not approaching the user, the electronic device 100 is kept in an original state and determines whether the electronic device 100 is approaching the user again.

It should be noted that S210 that it is determined whether the electronic device 100 is approaching the user may be implemented by the following manners.

Further, referring to FIG. 3, FIG. 4 and FIG. 9, in such an embodiment, S210 in which it is determined whether the electronic device 100 is approaching the user includes operations as follows.

At S2111, an environmental image is acquired.

At S2112, it is determined whether the environmental image contains a side face.

At S2113, it is determined that the electronic device is approaching the user in a case that the environmental image contains the side face.

S2111 may be implemented by the acquiring module 23, S2112 may be implemented by the judgment module 21, and S2113 may be implemented by the determining module 24. That is, the acquiring module 23 is configured to acquire an environmental image. The judgment module 21 is configured to determine whether the environmental image contains a side face. The determining module 24 is configured to determine that the electronic device 100 is approaching the user in a case that the environmental image contains the side face.

Further, in such an embodiment, the electronic device 100 includes a camera module 162 for capturing an image. The processor 10 is configured to acquire an environmental image captured by the camera module 162, determine whether the environmental image contains a side face, and determine that the electronic device 100 is approaching the user in a case that the environmental image contains the side face.

When the electronic device 100 is in an outgoing call state, an environmental image at a side opposite to the transparent display screen 13 may be captured by the camera module 162 of the electronic device 100 to determine whether the electronic device 100 is approaching the user. For example, whether the electronic device 100 is approaching the user can be determined by recognizing whether a face area is contained in a current environmental image and further recognizing whether an ear area is contained in the face area. Referring to FIG. 10, in a case that it is recognized that a side face area of the user is contained in the current environmental image and an ear area is contained in the side face area, it may be determined that the user has made the electronic device 100 approach him/her.

It will be appreciated that if it is detected that the environmental image does not contain the face area or the face image does not contain the ear area, it may be determined that the electronic device 100 is not approaching the user.

The face detection may be performed based on a preset portrait template, color, and the like in a database. In a case that a face exists in a recognized scene, a part connected to the face may be determined as a portrait area, and an implementation is not limited thereto. For example, it is also possible to determine the face by matching with the portrait template. It should be appreciated that recognition for the face area may also implemented by recognizing whether there is a continuous color block, and then recognizing a contour, so as to determine the face area and the ear area.

The camera module 162 may be a front camera of the electronic device 100. The camera module 162 may acquire an RGB image of an environment where the electronic device 100 is positioned. The camera module 162 may also be a depth camera. In a depth image, the nose, the eyes, the ears and other feature in the face area correspond to different depth data. For example, in a case that the side face faces the electronic device 100, in the captured depth image, depth data corresponding to the nose may be large, and depth data corresponding to the ears may be small. There may be multiple camera modules 162. For example, there may be two front cameras.

In addition, S210 that it is determined whether the electronic device 100 is approaching the user may also be implemented by the following manners.

Further, referring to FIG. 3, FIG. 4 and FIG. 11, in such an embodiment, S210 that it is determined whether the electronic device 100 is approaching the user includes operations as follows.

At S2121, a motion state of the electronic device is acquired.

At S2122, it is determined whether the motion state conforms to a predetermined motion state.

At S2123, it is determined that the electronic device is approaching the user in a case that the motion state conforms to the predetermined motion state.

Further, in such an embodiment, S2121 may be implemented by the acquiring module 23, S2122 may be implemented by the judgment module 21, and S2123 may be implemented by the determining module 24.

Further, in such an embodiment, the electronic device 100 includes an acceleration sensor 163 configured to detect a motion state of the electronic device 100. The processor 10 is configured to acquire the motion state of the electronic device 100 detected by the acceleration sensor 163, determine whether the motion state conforms to a predetermined motion state, and determine that the electronic device 100 is approaching the user in a case that the motion state conforms to the predetermined motion state.

It may be determined whether the electronic device 100 is approaching the user by detecting whether the electronic device 100 is raised by the user. In a case that it is detected that the electronic device 100 is raised by the user, it may be determined that the electronic device 100 is approaching the user. The hand-raising action of the user may be detected by a gyroscope, an acceleration sensor 163 or the other element of the electronic device 100. In general, the gyroscope may measure a rotational angular velocity of the electronic device 100 when the electronic device 100 is deflected and inclined. The acceleration sensor 163 may capture several typical motion modes of the electronic device 100 such as shaking, swinging and rolling over. The gyroscope and the acceleration sensor 163 may detect the motion state of the electronic device 100, such as raising, shaking and swinging. Therefore, it can be determined whether the user has an action of raising the electronic device 100 based on detection data from the gyroscope or the acceleration sensor 163. It should be noted that motion data on the predetermined motion state is set according to actual conditions, and is not limited herein.

Further, referring to FIG. 3, FIG. 4 and FIG. 12, in such an embodiment, S20 that control is performed to reduce the brightness of the transparent display screen 13 includes an operation as follows.

At S2131, current brightness of the transparent display screen is acquired.

At S2132, the brightness of the transparent display screen is reduced to a preset brightness based on the current brightness. The preset brightness is lower than the current brightness.

Further, in such an embodiment, S2131 and S2132 may be implemented by the control module 22. That is, the control module 22 is configured to acquire current brightness of the transparent display screen 13, and reduce the brightness of the transparent display screen 13 to a preset brightness based on the current brightness. The preset brightness is lower than the current brightness.

Further, in such an embodiment, the processor 10 is configured to acquire current brightness of the transparent display screen 13, and reduce the brightness of the transparent display screen 13 to a preset brightness based on the current brightness. The preset brightness is lower than the current brightness.

In a case that the brightness of the transparent display screen 13 is reduced to the preset brightness, the effect of the flickering caused by the infrared light emitted by the infrared sensor 161 on the transparent display screen 13 can be weakened, which more facilitates improvement of the user experience.

Further, referring to FIG. 13, in such an embodiment, S20 that control is performed to reduce the brightness of the transparent display screen 13 includes an operation as follows.

At S202, control is performed to reduce the brightness of the window area.
